To all whom it may concern Be it known that. ll, WILLIAM A. PRINGLE,

a citizen of the United States,,residing at Niagara Falls, in the county of Niagara and State of New York, have. invented certain new and useful Improvements in Web-;

Transforming Mechanisms, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates .to web handling mechanism, and with regard to the more specific features thereof, to mechanism for transforming a web into printed sheets adapted to be bound into salesbooks of various styles.

One of the objects of this invention is to provide a single self-contained piece of apparatus adapted to transform a continuous web into printed sheets of either the continuous, folded or fiat form at will.

Another object is to provide mechanism of the above character of simple and readily adjustable form. 1

Other objects are to provide practical and eflicient mechanism for cutting and for perforating a web.

Other objects will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combination of elements and arrangement'of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claim.

' In the accompanying drawings wherein is shown one of many possible embodiments of my invention, Figure 1- denotes a side elevation of the complete apparatus, certain parts being shown diagrammatically for the sake of clearness; Fig. 2 is'a detailed end view of the cutting and perforating mechanism, partly in section; Fig. 3 is a plan view of one end of the cutting and perforating roller; Fig. 4 represents a tie tailed vie of a part of one of the rollers.

Fig.5 is a plan view of the fiat delivery receiving mechanism.

Similar reference characters refer tosimilar parts throughout the several views of the drawings.

Referring to these drawings in detail, the general construction comprises a standard 1 "herein shown in detail. The rol a roll of paper web 2 which is adapted to pass around a printing cylinder 3 suitably inked by inking mechanism 4 over a platen roller 5 to-tension members 6 for'the purpose of printing at regular intervals head- 'ings for, each sheet denoting the store in which the salesbook is to be used, for example. The web may then be conducted to continuous fold mechanism, which is shown diagrammatically at 7, as the same is .a complicated apparatus and forms no part of the present invention specifically; or, if desired, the web may be conducted to suitable conveying and tensioning means 8 from whence it passes to suitable mechanism hereinafter described in detail, to be out for flat delivery or cut and folded for folded delivery. The last mechanism forms a portion of the subject matter of my co-pendlng application for web handling mechanism filed January 17, 1910, Serial No. 538,382, and

need not be herein described in detail.

The mechanism above referred to comprises a suitable support or standard 9 having mounted thereon a frame 10 carrying a plurality of rollers, one of which, 11, mounted at the upper part of the frame, is adapted to co-act with the platen roller 5 of the printing mechanism and to be driven therefrom by means of any suitable caring, not

er 5 is provided with a protruding boss 12 at each side corresponding to a similarlyprotru'ding portion 13 of the roller 11. A link 14 having recessed portions 15 is adapted to fit over these protrudin parts 12 and 13 whereby the rollers 5 an 11 are clamped in co-active relation. It is thus seen that by removing the link 14 the entire mechanism for forming fiat delivery or folded sheets may be disconnected from the driving means when it is desired to use the continuous fold mechanism alone. drives a roller 15 provided with a folding blade 16 (Fig. 2) co-acting with gripper mechanism 17 mounted on the roller 18 for forming folded sheets. As this mechanism is fully described inmy above mentioned application a further discussion of the same will not I be repeated. Substantially diametrically opposite the folding blade 16 is provided a cutting blade 19, a movable perforator blade 20, and movable holding pins 21 co-acting with the member 22 mounted The roller 11 co-acts with and,

adapted to hold at theupper part thereof in the roller 18 provided respectively with a recess 23, a serrated edge 24, and recesses 25. The block 22 mounted in the roller 18 is preferably composed of two parts forming the recess 23, one of these parts being provided with a sharpedge 26 adapted to co-act with the cutter blade 19 whereby the web, as the same is conveyed between the rollers, is given a smooth edge at the bottom of one of the sheets anda roughened edge at the top of the following sheet, the smooth edge, of course, givin the pad a neat appearance, while the finis of the top edge is immaterial, the same being bound into the pad or book. The cutting blade 19 is preferably of saw-toothed construction fOIi) the purpose of more easily cutting the we The perforator blade 20 co-actin'g with the serrated edge 24 forms a line of perforations in the paper near the 'top thereof whereby the same may be easily torn off from the pad. The perforating blade 20 is preferably of saw-toothed construction also co-acting with the serrated edge 24 in such manner as to positively prevent a severance of the web at this point. The pins 21 are .provided for engaging the web when making folded sheets immediately after the per-' forator blade is withdrawn to carry the paper around the roller 15' when they are withdrawn simultaneously with the actuation of folding mechanism 16 and 17.

' These pins 21 are few in number and are actuated by means of arms 27 mounted on a rock shaft 28 having at one end thereof a roller carrying arm 29 adapted to co-act with a stationary cam member 30 mounted at one side of the frame of the machine. These parts are normally held in retracted position by means of spring mechanism 31 mounted on the rock shaft. The reciprocating perforator blade 20 is actuated in a. somewhat similar manner by means of arms 32 mounted on a rock shaft 33 having at one end thereof a roller carrying arm 34 co-acting with a cam member 35 at the opposite end of the roll. This cam member is so formed as to gradually advance the perforator blade till it acts on the paper and then quickly withdraw the same. It will thus be seen that as the roller 15' rotates in the direction of the arrow (Fig. 2) the rock shafts 28 and 33 will be rotated to actuate the perforator blade and holding pins at the proper moment, it being understood, of course, that the cam members are adjustable about their supports, as by a pin andslot' construction 36, or the like, for varying circumstances, as are the supports carrying the folding blade 16, cutting blade and perforator, by means of slot and set screw mechanism 37, for

providing sheets of various sizes. The folding mechanism and the co-acting parts for the cutting and perforatmg mechanism upon the roller 18 are likewise adjustable by similar mechanism 38.

Referring now to the folded sheet delivery mechanism, which is shown more clearly in Fig. 1, a suitable frame 39 is clamped about the standard 9 below a stripper roller 40 c0- acting with the roller 18 and driven therefrom. Mounted on this frameis an oscilmeans'of a link 42 with the roller 40 whereby it is given an oscillatory movement. A second link 43 connects this oscillating wheel 4 with a crank arm 44 mounted in the up- 'veniently handled for binding.

The upper part of the standard 9 is pro- 'lating wheel 41 connected eccentrically by vided with a recess 50 adapted to receive a pin carried by the flat delivery receiving mechanism, now about to be described,

whereby the same may be'easily and quickly applied when flat delivery sheets are desired, the mechanism for forming folded sheets being detached. This. mechanism comprises a frame 51 carrying at the forward part thereof a gear 52 adapted to be driven from the roller 18 in any well known manner. This gear drives throufgh gearing 53 a pair of feed rollers 54 for eedin the severed sheets from a stripper blade 54 into a receiving box 55 where they are engaged in the usual manner by a fly 56 mounted on a rock shaft 57 which is oscillated through a link 58 carrying a roller 59 at one end thereof adapted to co-act with a cam 60 at one end of the roller 15, as shown in Fig. 1.- The' link 58 is normally urged to the position shown in Fig. 1 by means of a spring 61 on the rock shaft 57 and is moved therefrom by the cam 60, the fiat portion of which allows the arm 53 to be drawn toward the left at regular intervals in order that the arms 56 may pile the sheets in superimposed relation. V

The feed rollers 54 are provided at one end with a worm 62 meshing with a gear 63 for rotating a roller 64 around which passes an endless belt 65 over a similar roller 66 at the opposite side of the belt. In this manner the endless belt 65 is gradually conveyed to one side of the machine in order that the sheets may be piled in staggered relation. It is thus seen that this mechanism provides for a simple and practical selfcontained device in which the parts may be easily shifted, attached and removed in order to produce sheets suitable for use in manifolding books of various well known styles.

As many changes could be made in the above construction and many apparently .Widely different embodiments of this invention could be made without departing. from the scope thereof, it is intended that all matter Contained in-the above description or sho .n in the accompanying drawings. shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claim is intended to cover all of the generic and specific featuies of the invention herein described and all statements of the scope of the invention, which, as a matter of language, mi ht be said to fall therebetween.

aving described my invention, what I claim as new and desire to secure by Letters Patent is:

In apparatus of the character described, in combination, web printing mechanism, means adapted to fold a Web transversely,

means adapted to cut the web into single sheets, means adapted to deliver folded sheets, means adapted to deliver the single sheets, and feeding means, a portion of which is common to the means for delivering the folded sheets and the means for delivering the single sheets.

In testimony whereof I aflix my signature, in thepresence of two Witnesses.

WILLIAM A. PRINGLE.
